1 Claim. (Cl. 20-522)
This invention relates to windows of the double hung
or sliding sash type, and particularly windows wherein
weights and other balancing elements are eliminated, and
in particular a window having sash with longitudinally
disposed undulating strips on opposite edges thereof
wherein the undulating strips are positioned to coact with
complementary spring actuated longitudinally disposed
strips in the sides of a window frame, whereby the sash
are readily adjusted vertically in the window frame and
wherein the sash are readily removable to facilitate clean
ing and repairing, and also readily replaceable.
The purpose of this invention is to provide a window
of the double hung type in which weights and other bal

elements in which the window is of simple and economical
construction.
With these and other objects and advantages in view
the invention embodies a window frame, sash slidably
mounted in the window frame and separated by parting
strips, undulating strips of material on the edges at the
sides of the sash, complementary undulating strips of
material in the sides of the window frame and positioned
to coact with the undulating strips on the sash, and
springs positioned behind the undulating strips of mate-'
rial in the window frame for urging the undulating strips
of the frame into engagement with the undulating strips
of the sash.
Other features and advantages of the invention will
appear from the following description taken in connec
tion with the drawings, wherein:
